Call Flows

New ConceptsContact Object Based Routing

Provides static routing of phone numbers to destinations such as applicationsAn AD contact object is created for each access number with the following information:

SIP AOR (Address of Record)Phone number (For RNL)Display phone numberAssociated poolApplication typeApplication destination (GRUU)

New ConceptsTrusted Conferencing Identities

OCS allows applications join a conferencing with trusted conferencing identities (services)Trusted conferencing services can send requests to conference without getting challengedA GRUU is associated with each trusted conferencing service, so OCS can route a request to the application’s listening portTrusted conferencing services can:

Impersonate a conferencing user (i.e. CA)Act as a “trusted bot” (i.e. CAS)

Reporting and Monitoring

Conference DirectoryWhat is it?

A mapping of to Conference IDs to Conference URIsWhy do we need it?

It is necessary to convert SIP URIs to numeric only ids input from numeric entry systems (such as PSTN)

What is its impact?No end user impactAdmins need to maintain Conference Directories (Disaster Recovery, Decommissioning Pools, Moving Pools)

Related TermsDirectory ID: a short numeric ID used to identify a conference directoryConference Resolution: Process of mapping a conf ID to a conference URI

Reporting and CDRMain data points captured for conferences

Conference URIConference start timeConference end timeUser join timeUser leave timeUser join time to conferencing servers (A/V, Data, IM etc)User leave time from conferencing serversJoin via PSTN (For A/V Conferences only)

Reports can be filtered by:Dates (Admins can choose

weekly, monthly)Participant Count/

Performance Counters in SCOMSome key Performance Counters collected by the OCS Management Pack

Incomplete Calls per sec, Total Incomplete callsTotal calls successfully transferred to conferenceCurrent & Total # of Calls on Music on Hold (MoH), Calls Timed out on MoHTotal Calls from UC ClientTotal # of Mute/Un-Mute/Entry/Exit announcementsCurrent & Total # of attendees that have joined conferences, Current & Total # of active personal announcersCurrent & Total # of conference attendees

Performance Counters hold data since the last restart of OCS 2007 R2

Capacity and Scalability

Component Supported PerformanceConferencing Attendant 450 simultaneous calls (based on a

computer with 8 processor cores running at 2.33Ghz, and 4GB of memory)

Collocated Access Edge & Web Conferencing Edge Server

Access Edge Server:  5,000 client connectionsWeb Conferencing Edge Server: 1,500 client connections

Collocated Access Edge, Web Conferencing Edge and A/V Edge Servers (Consolidated Edge Topology)

Access Edge Server:  5,000 client connectionsWeb Conferencing Edge Server: 1,000 client connectionsA/V Edge Server 500 concurrent audio/video sessions

Bringing it together: Scenario
